Production of n - phosphorus phonological methyl glycine by oxidation of n - of phosphoric acid phonological methyl imino this.

摘要

AS THESE IMPROVEMENTS TO A PROCEDURE FOR OBTAINING N-phosphonomethylglycine by oxidation of N-phosphonomethyliminodiacetic acid, N-phosphonomethylglycine may be obtained by oxidation of N-phosphonomethyliminodiacetic acid with OSI2 or a gas containing it, in the presence of metal catalyst NOBLE ON CARTON ACTIVE. TO PREVENT LOSSES CATALYST IMPROVEMENTS the invention are PERFORM PRESSURE WITH SWEEP NSi2, once the oxidation reaction. This treatment catalyst losses decreased from 30% to 1%, SO THE PROCEDURE economic feasibility at industrial level. THE CATALYST RECOVERED AND KEEPS HIS catalytic activity can be reused by at least 20 times consecutively. N-phosphonomethylglycine IS A VERY herbicide widespread application.
